General Formulas

Cylinder output forces are derived from the following formula:

F = P X A

F= Force in pounds

P= Pressure at the cylinder in pounds per square inch, gauge

A= Effective area of cylinder piston in square inches


Free Air refers to the normal atmospheric conditions of air at sea level (14.7 psi). Use the above "cu. ft. free air required" data to compute CFM required from a compressor at 80 psi. Cu. ft. of free air required at other pressures can be calculated using the following formula:

V1= (P+ 14.7) V2 / 14.7

V1= Free air consumption per inch of stroke (cubic feet)

V2= Cubic feet displaced per inch of stroke

P2= Gauge pressure required to move maximum load
